the left STP of \(A\)  and \(B\) , denoted by \(A\ltimes B\) , is
defined as
\(A\ltimes B:=\left(A\otimes I_{t/n}\right)\left(B\otimes I_{t/p}\right),\) 

where the \(\otimes \)  is the Kronecker product [1]};

the right STP of
\(A\)  and \(B\)  is defined as
\(  A\rtimes B:=\left(I_{t/n}\otimes A\right)\left( I_{t/p} \otimes B\right).\)
